You open your latest energy bill, and it’s higher than ever. But you haven’t changed much in your routine, so why is it climbing?
The truth is, there’s more to energy bills in Australia than how much electricity or gas you use. They’re made up of a mix of fixed daily fees, usage charges, and even extra costs like network maintenance or billing add-ons. Whether it’s your Gas Rate or your electricity tariff, understanding what you’re really paying for is the first step to keeping costs under control.
In this guide, we’ll break down for you how your energy bill is calculated in Australia, explain the difference between electricity and gas charges, and show you how to compare Energy Australia with other providers to see if you’re getting the best deal.
The Two Main Parts of Your Energy Bill
Every Aussie household pays two types of charges, no matter which retailer you’re with:
1. Fixed (Supply) Charges
This is the daily fee you pay just to be connected. It covers things like poles, wires, meters, and infrastructure maintenance. Even if you use almost no energy during a billing period, this charge stays the same.
2. Usage (Variable) Charges
This is based on how much energy you actually use. For electricity, it’s measured in kilowatt-hours (kWh). For gas, it’s measured in megajoules (MJ).
Basic formula:
Total Bill = (Daily Supply Charge × Days) + (Usage × Rate per Unit) + Taxes/Adjustments
Knowing this breakdown helps you see where your money’s going and where you can save.
Electricity Bill Breakdown
Electricity bills often look complicated, but each section matters. Here’s what’s usually included:
- Usage Charges (cents per kWh): The cost per unit of electricity you consume. For example, at 30c per kWh, using 500 kWh would cost you $150.
- Time-of-Use Tariffs: Prices change depending on when you use power.
- Peak hours (e.g. 2–8 pm): most expensive
- Off-peak (late night/early morning): cheaper
- Shoulder: in between
- Daily Supply Charge: Flat fee for keeping your electricity connected, usually $1–$1.50 per day.
- Network Costs: Charged by distributors for maintaining poles and wires.
- GreenPower/Extras: If you choose renewable energy options, you’ll pay a small extra per unit.
- GST & Adjustments: Every bill includes 10% GST and sometimes corrections for estimated meter reads.
💡 Tip: Run your washing machine, dishwasher, or pool pump during off-peak hours to cut down your bill.
Gas Bill Breakdown: What Your Gas Rate Really Means
If you’re using gas for heating, cooking, or hot water, your gas rate plays a big role in your bill.
- Gas Usage Charge: Measured in MJ, usually between 2–4c per MJ depending on your provider and location.
- Daily Supply Charge: About $0.80–$1.00 per day just to stay connected.
- Network Costs: Fees for transporting gas through pipelines.
- Retailer Margin: A small markup added by your retailer for service and billing.
Example:
If your gas rate is 2.5c/MJ, you use 800 MJ, and your supply charge is $0.90/day for 30 days, your gas cost is about $52.50.

Extra Fees, Discounts, and Adjustments
Bills often include extras that can either save or cost you money, such as:
- Discounts: for paying on time or using direct debit
- Paper billing fees: you can often save by going digital
- Late payment penalties
- Solar feed-in credits: if you export excess solar power
- Government rebates/concessions: for eligible households
- Estimated meter reads: (which might be corrected later)
These small line items add up, so always check your bill carefully.
Why Does Your Energy Bill Change Month to Month?
Even if you’re on the same plan, your bill can still change. Here’s why:
- Seasonal usage: Heating in winter and air-con in summer spike usage.
- Peak-time habits: Running appliances during expensive hours raises costs.
- Lifestyle changes: Working from home, new appliances, or guests staying over.
- Wholesale price shifts: Retailers may increase tariffs when market prices go up.
- Estimated bills: Charges based on estimates can be higher or lower than actual reads.
🔍 Tip: If you see “estimated” on your bill, submit your own meter reading for accuracy.
How to Compare Energy Australia and Other Providers?
Once you know what makes up your bill, you can make smarter choices. Here’s how:
- Grab your latest bill and note your supply charge and usage rate.
- Check your average daily usage.
- Use a comparison tool like DealExpert to compare Energy Australia rates with others in your area. These tools are quick and easy to use.
- Look at both electricity and gas; bundled plans may give extra savings.
- Read reviews to see which retailers actually deliver good customer service.
👉 Don’t assume the “Big 3” (Energy Australia, AGL, Origin) are always cheapest. Smaller retailers often undercut them.
Common Billing Traps to Avoid
Even savvy households make these mistakes:
- Choosing a plan with a low usage rate but a high daily supply charge
- Staying on an expired discount plan
- Ignoring peak/off-peak tariffs
- Forgetting to check bills for errors or estimated reads
- Believing big brands are always the cheapest
- Not comparing plans at least once a year
Avoiding these traps can save hundreds every year.
